Tomoki Hiwatashi's interview during women's free program warm up (group 3) at 4CC

I wanted to ask you guys about your thoughts on his comments. He was asked about his coaching change (to Mie Hamada) and he said he decided to go to her because she wanted to change technique and that he agreed with her and her technique. I am not familiar with Tomoki and his aspirations, so maybe you guys can enlighten me. Does he want to add more quads to his repertoire? That's the only reason I could think for him changing to Mie given what we know about Mie and what it is said about her.
